Radiation Interaction with Matter Quiz

What is the photoelectric effect?

• The photoelectric effect is the reflection of light by a material

• The photoelectric effect is the transmission of light through a material

• The photoelectric effect is the emission of electrons from a material when it is exposed to light.

• The photoelectric effect is the absorption of light by a material

What is pair production in the context of radiation?

• The creation of a neutron and a proton from a neutral boson

• Creation of a subatomic particle and its antiparticle from a neutral boson

• The emission of a photon by an atomic nucleus

• The absorption of a photon by an atomic nucleus

Define attenuation in the context of radiation.

• Increase in the intensity of radiation as it passes through a material or medium

• Attenuation refers to the speed of radiation as it passes through a material or medium

• Attenuation is the process of converting radiation into a different form of energy

• Reduction in the intensity of radiation as it passes through a material or medium

How does Compton scattering differ from the photoelectric effect?

• Compton scattering involves the absorption of X-rays by free electrons.

• Compton scattering does not involve the interaction of X-rays with electrons.

• Compton scattering results in the emission of X-rays by free electrons.

• Compton scattering involves the scattering of X-rays or gamma rays by free electrons.

What are the conditions required for pair production to occur?

• Low energy and momentum

• High temperature and pressure

• Interaction with a nucleus or an electron

• Interaction with a photon

Explain the concept of linear attenuation coefficient.

• It measures the color change of a material when exposed to radiation

• It measures how a material reduces the intensity of radiation as it passes through

• It measures the speed of radiation as it passes through a material

• It measures the temperature change of a material when exposed to radiation

How does the energy of the incident photon affect Compton scattering?

• It affects the scattering angle and the kinetic energy of the scattered photon.

• It causes the incident photon to change direction but not energy

• It has no effect on Compton scattering

• It only affects the color of the scattered photon
